CAR-STAKE CAP.

SPECIFICATION forming part of Letters Patent No. 770,096, dated September 13, 1904.

Application filed July 14, 1904, Serial No. 216,551. (No model.)

To all whom it may concern.-

Be it known that I, ANGUS A. MoIN'rosH, a

citizen of the United States, residing at Escanaba, in the county of Delta and State of Michigan, have invented certain new and usefulImprovements in Car-Stake Caps; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a device to facilitate loading or piling logs or timbers, and is especially adapted for loading logs on fiat-cars, where the logs are loaded lengthwise the car by being rolled up inclined skidways and delivered on the car over the tops of the car-stakes.

The objects of my improvement are to produce a cap to be temporarily attached to the top of a car-stake and adapted to not only hold up the horizontal supporting-beam, on which the upper ends of the inclined skidway rest, but also to clamp the supporting-timber firmly in contact with the top of the carstake, the force with which the supportingtimber and stake are clamped together increasing as the load on the skidway increases.

With these and certain other objects, which will appear later in this specification, in view my invention consists in certain devices illustrated in the accompanying drawings, in which Figure l is a side view of a car-stake cap. Fig. 2 is ahorizontal section taken on the line a: m of Fig. 1. Fig. 3 isan end view of acar partly loaded with logs, showing the manner of using my improvement.

As is clearly shown in the drawings, the device consists in a hollow cap 1, of cast-iron or other suitable material, of suitable size and shape to drop down over the top of a carstake or other timber on which it is to be used. The top 1" of the cap is preferably rounded to avoid catching on the log. Projecting outwardly and upwardly from the lower part of the cap is a curved arm or hook 2, upon which rests the skid-supporting beam 3. Part of the wall of the cap 1 opposite the hook 2 is cut away, as shown at 4 in Fig. 1, and the car-stake 5 is exposed through the recess thus formed.

The inclination of the arm 2 is such that the skid-supporting beam 3 naturally drops into the angle between the stake and arm and is clamped or wedged between them. Suitable reinforcing-ribs 1 and 2 are provided on the cap and arm.

When the log is at the lower end of the skidway, less clamping effect is produced than when the log is near the upper end of the skidway. This increased clamping effort takes effect when the log is elevated and where the greatest holding power is needed.

A further advantage of this construction is in the fact that the cap will hold almost equally well whether the end of the stake exactly fits the cap or not, since to make the cap, the supporting-beam, and the stake firmly interlock it is only necessary to have the three in contact, as above described. This contact is secured regardless of whether or not the cap fits the stake exactly. Being simple in construction and formed ofa single piece of metal, it is not easily damaged and is well suited to the rough usage to which it is subjected. It can be quickly changed from one stake to another without the use of bolts, screws, or other fastening devices.

What I claim as my invention, and desire to secure by Letters Patent, is as follows:

1. The combination with the hollow cap of an upwardly and outwardlyinclined arm; said cap having a recess in its wall opposite the inclined arm.

2. The combination with the hollow cap formed with a rounded top; of an upwardly and outwardly inclined curved arm having reinforcing-ribs; said cap having a recess in its wall opposite said inclined arm.

3. The combination with the hollow cap, of an upwardly and outwardly inclined curved arm formed integral with said cap; said cap having a recess in its wall opposite said inclined arm, for the purposes set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

ANGUS A. MCINTOSH.
